Precision Twist Drill 6000702 Cobalt Jobber Drill 7.20mm

Product Description

The PRECISION TWIST DRILL 6000702 is a cobalt jobber-length drill bit engineered for general-purpose drilling in steel and other demanding workpiece materials. Built to DIN 338 and ANSI standards, it features a 135-degree split point with web thinning for fast engagement and reduced walking on entry. The straw oxide finish provides light lubricity and heat resistance during cutting. With a 7.20 mm diameter, a 4-19/64 inch overall length, and a 2-flute right-hand spiral flute design, this bit suits production and maintenance drilling applications where durability and consistent hole geometry are required. Licensed tradespeople and machining professionals select this series for heavy-duty jobber work.

This drill bit is designed for use in ferrous metals including carbon steel, alloy steel, cast iron, and non-ferrous materials. The cobalt substrate and heavy-duty grade make it appropriate for harder steels that wear out standard HSS tooling. It is well suited for use in drill presses, CNC machining centers, and hand-held drilling equipment where a straight cylindrical shank is the standard interface. Typical applications include fabrication shops, mechanical service work, and field maintenance requiring a reliable metric-size hole in steel.

Key Features

• Cobalt construction for heavy-duty performance in ferrous and hard materials
• 135-degree split point with web thinning reduces thrust and minimizes bit walking
• Straw oxide finish improves lubricity and heat resistance at the cutting edge
• Right-hand, regular spiral flute geometry for efficient chip evacuation
• Straight cylindrical shank fits standard drill chucks without adapters
• Conforms to DIN 338 and ANSI specifications for dimensional consistency

Compatibility

Designed as a general-purpose jobber drill bit compatible with any drill press, machining center, or hand-held drill accepting a 7.20 mm (0.2835 inch) straight cylindrical shank. Suitable for primary workpiece material codes P, M, K, N, and S per ISO material classification.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or maintenance tradespeople familiar with proper tooling setup. Secure the shank fully in the chuck and verify runout before drilling. Always power down and lock out the machine before changing tooling. Use appropriate cutting fluid or lubricant when drilling steel to extend tool life and maintain hole quality.
